Let's divide 84478866 by 806
The aim is to understand the frequency of 806 in 84478866.

Going ahead to step 1:
806 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 806

On to step 2:
When dividing 84 by 806, we get 0 with a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 806

Step 3:
844 divided by 806 is 1 with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 806 from 844 leaves us with 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 806

Advancing to step 4:
If we divide 387 by 806, we get 0 and a remainder of 387.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 387, we get 387.
Fetch the next digit (8) from the dividend, attach it to 387 and continue: 3878 / 806

Moving on to step 5:
3878 divided by 806 is 4 with a remainder of 654.
Put 4 as the next digit of the answer. 
Result so far: 104.0
The remainder is 654 after subtracting 3224 from 3878.
Fetch the next digit (8) from the dividend, attach it to 654 and continue: 6548 / 806

On to step 6:
806 can be fit into 6548 8 times, resulting in a remainder of 100.
The next digit of our result is 8. 
Result so far: 1048.0
If we subtract 6448 from 6548, we get 100.
Fetch the next digit (6) from the dividend, attach it to 100 and continue: 1006 / 806

On to step 7:
The number 806 fits into 1006 1 times, leaving a remainder of 200.
Write down 1 as next digit of the result. 
Result so far: 10481.0
Deduct 806 from 1006 and we're left with 200.
Take the next digit (6) from the dividend and append it to 200, then repeat: 2006 / 806

On to step 8:
2006 divided by 806 is 2 with a remainder of 394.
Record the quotient 2 as the next digit in the result. 
Result so far: 104812.0
Subtracting 1612 from 2006 leaves us with 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 9:
806 can be fit into 3940 4 times, resulting in a remainder of 716.
Write down 4 as next digit of the result. 
Result so far: 104812.4
The remainder is 716 after subtracting 3224 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Advancing to step 10:
The number 806 fits into 7160 8 times, leaving a remainder of 712.
The number 8 becomes the next digit in our result. 
Result so far: 104812.48
The remainder is 712 after subtracting 6448 from 7160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Going ahead to step 11:
The number 806 fits into 7120 8 times, leaving a remainder of 672.
Record the quotient 8 as the next digit in the result. 
Result so far: 104812.488
Subtracting 6448 from 7120 leaves us with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Our division results in 104812.488 with a remaining 0.0672.
